<p>Many people prefer <a href="http://daringfireball.net/projects/markdown/" target="_blank">Markdown</a>
  over standard HTML because it is less verbose. Unlike Textile, Markdown
  doesn&#8217;t try to replicate all of the features implemented by regular
  HTML, instead it encourages the use of inline HTML. Markdown is very similar
  to the formatting used in a standard plain-text e-mail. This filter also uses
  <a href="http://daringfireball.net/projects/smartypants/" target="_blank">SmartyPants</a>
  to curl quotes and insert correct punctuation.</p>
